Abstract

The invention relates to a continuous preparation method of composite material tube, comprising two basic processes of: (1) winding: winding a circle on a surface to be processed after the continuous fiber prepreg is pre-heated and forming a prepreg winding layer; and (2) binding: binding the continuous fibers of the impregnated resin matrix glue solution to the surface to be processed, wherein the fibers are neither overlapped nor separated and are distributed to the surface to be processed uniformly and continuously to form a fiber binding layer; when layering, the process (1) and the process (2) are carried out in turn on the same device; and the composite material tube is formed through curing and demoulding. According to the invention, the fiber layering layer of the fiber enhanced composite material tube can be layered at any angle from 0 to 90 degrees through the manner of winding fibers and binding prepreg in turn; and the fiber enhanced composite material tube has higher circumferential strength, excellent axial strength and bending rigidity.

Description

technical field [0001] The invention relates to a continuous preparation method of a composite material pipe, in particular to a continuous preparation method of a fiber-reinforced composite material pipe. Background technique [0002] Fiber-reinforced composite pipe is a composite material product, and common reinforcing fibers include glass fiber and carbon fiber. Compared with traditional metal pipes, it has the advantages of light weight, high strength, and strong corrosion resistance. It can be used to replace metal materials as various structural parts. It is used in many fields such as aerospace, automobile manufacturing, and textile machinery. widely used. [0003] Fiber-reinforced composite tubes are usually prepared by winding molding or tube rolling molding. Winding molding means that continuous fibers soaked in resin matrix glue are wound on the mandrel according to a certain rule under tension, and after reaching a certain thickness, they are cured, obtained f...
